2. Description of the Prior Art

Since BHC and DDT have been developed, remarkable advances have been made in the organic agricultural agents such as phosphorus agents, carbamates, pyrethroids and the progress of such organic agricultural agents now establishes a certain close correlation between the consumed quantity of pesticides and the harvested quantity of crops. However, on the other hand, these agricultural agents have caused pollutions by the environment contamination and at present there are many problems such as the accumulation of toxicity and the chronic toxicity as well as the generation of a wide variety of pesticide-resistant noxious insects. The desirable requirements for pesticides are, therefore, that the active pesticides exhibit a low toxicity, a low residual and a rapid decomposition and they are converted into non-toxic materials upon entrance into one of the biological cycles of the ecological system. In particular, the compounds containing no heavy metals nor halogen atoms and composed mainly of carbon, hydrogen and oxygen are considered to be advantageous as agricultural agents.

The active groups of the pesticides presently used include organic phosphorus compounds, carbamates, chrysanthemic acid esters, organochloric compounds, etc., and most of the researchers in this field now endeavour to develop new types of pesticides by considering the superiority or inferiority of each of the above active groups and screening various synthetic derivatives retaining only the superiority of the known pesticides.

The present inventors considered that each of the above well-known active groups has certain properties as basic pesticidal characteristics inherent to the specific active group and that the disadvantages associated with the specific active group would not be eliminated unless departing from the above specific properties. As a result of extensive researches for active groups having novel chemical structures, the present inventors found the new and useful acetic acid esters represented by the above formula (I).

The compounds of this invention have various advantages broadly and also exhibit strong selectivity, and the chemical structures retaining only properties advantageous as agricultural agents can be considered depending upon the specific type of the compounds of this invention.

Hithertofore, esters which are considered to be pesticidal active groups, for example, phosphoric acid esters and chrysanthemic acid esters are believed to have their activities in the basic structures of phosphoric acid and cyclopropanecarboxylic acid, respectively. These esters contain a S (or O) atom bonded to a pentavalent phosphorus by a double bond as an essential structure of the phosphoric acid esters and a three-membered ring as an essential structure of the chrysanthemic acid esters, respectively, and the pesticidal activity tends to be strengthened or weakened depending upon the type of moieties present around the above essential structure as a nucleus.

In the compounds of this invention, the acid moiety represented by the formula (XI) ##STR19## is considered to be an important active basic structure, and its essential structure is completed by a hydrogen atom at α-position of the ester group, an appropriate substituent (Z) and a substituent (Y) which are characterized in its plane structure. On the other hand, the alcohol moiety of the ester corresponds to the alcohol moiety of the well-known chrysanthemic acid esters as shown by the examples of compounds described below, but, in accordance with the present invention, it was found that highly active pesticides can be prepared by esterification of the acids represented by the formula (XI) with the above alcohol moiety and that the compounds having a surprisingly high selectivity can be prepared by using an appropriate combination of an acid moiety and an alcohol moiety. However, the order of activity of the ester composed of the known alcohol and the known acid cannot be applied as it is to the evaluation of the activity of the esters in accordance with the present invention since the esters of this invention exhibit activities entirely different those of the known esters. Accordingly, the esters composed of the acid used in the present invention and the alcohol which has been found to form a highly active ester in the known pesticides do not necessarily exhibit an excellent activity.

In addition, in accordance with the present invention, various advantages such as immediate onset of action, permeability, transfer into living plants, residual activity, pesticidal activity, metamorphosis disturbance, sterilization, prohibition of egg-lying can freely be controlled by appropriately selecting a combination of an acid of the present invention and a wide variety of alcohols. Also, with respect to the spectrum of pesticidal activity, the compounds of this invention exhibit a selective or non-selective activity on such order as Coreoptera, Lepidoptera, Diptera, Orthoptera, Hemiptera, Homoptera and Acarus depending upon a specific combination of acid and an alcohol according to the present invention. Further, the compounds of this invention are expected to be useful for controlling noxious insects such as a nematoda. Other important features of the compounds of this invention are that they are active against noxious insects which are resistant to the pesticides presently used because of their basic structure different from those of the known pesticides to which the insects are resistant, and that they are totally low toxic to mammals including man as indicated by Experiments shown below.

As the results of the present invention, the substituted acetate compounds of the formula, ##STR20## wherein R'₁ represents straight or branched chain alkyl having 1 to 4 carbon atoms, halogen or alkoxy having 1 to 4 carbon atoms; R'₂ represents hydrogen or a group which completes, together with R'₁, methylenedioxy; and X' represents a group of the formula, ##STR21## are more excellent in insecticidal effect, a killing effect and a knock down effect than the other substituted acetate compounds of the formula (I).

In order to make the above fact clearer, the superiority of the compounds represented by the formula (I') in biological effects is shown below with reference to Experimental Examples. But the other compounds of the formula (I) and their geometrical isomers and optical isomers display more excellent effects as well than the known insecticidal agents.

In preparing the substituted acetic acid esters represented by the formula (I), an acid represented by the formula ##STR22## wherein Y and Z are as defined above, or a reactive derivative thereof is reacted with an alcohol represented by the formula

    X--OH                                                      (XII)

wherein X is as defined above, or a halide or sulfoxylate thereof.

The term "reactive derivative" of the acid used herein refers to an acid halide, an acid anhydride, an ester with an alcohol having a low boiling point, and an alkali metal salt, a silver salt or an organic tertiary base salt of the acid.

The substituted acetic acid esters represented by the formula (I) include optical isomers due to the carbon atom at α-position, and it is to be understood that the present invention is contemplated to include optical isomers.

In carrying out the production of the substituted acetic acid esters of the formula (I), the esterification between the acid (XI) and the alcohol (XII) can advantageously be accomplished by reacting the reactants in an appropriate inert solvent at room temperature or an elevated temperature under an appropriate dehydrating condition, e.g., in the presence of cyclohexylcarbodiimide. When an acid halide is used as a reactive derivative of the acid (XI), the desired ester can be obtained in high yield by reacting the alcohol (XII) and the acid halide at room temperature using an acid acceptor, for example, an organic tertiary amine such as pyridine, triethylamine and the like. The acid halides which can be used in the process of this invention may be any type of halides within the scope of this invention, but an acid chloride is generally preferred. The presence of an inert solvent is not essential in the esterification reaction, but it is generally preferred to use a solvent in order to assure a smooth reaction. Any solvent which is inert to the reactants and the ester product may be used and a preferred inert solvent includes benzene, toluene and petroleum benzine. When an ester of the acid (XI) and a low boiling point alcohol, e.g., methanol, ethanol and the like is used as a reactive derivative of the acid, the desired ester (I) can be obtained in high yield by heat-reacting the ester and the alcohol (XII) with heating in the presence of an appropriate organic base catalyst, preferably, an alkali metal alkoxide corresponding to the low boiling alcohol of the ester used or sodium hydride in an inert solvent such as toluene while removing a low boiling alcohol liberated during the reaction from the reaction system by a fractional distillation column.

In an alternative esterification procedure using an acid anhydride as a reactive derivative of the acid (XI), the desired ester can be obtained by reacting the acid anhydride with the alcohol (XII) at room temperature without using specific reaction aids. In this case, it is preferred to heat the reaction system and to use a solvent such as toluene, xylene and the like in order to ensure a smooth reaction, but the heating and the use of solvent are not critical in this procedure.

When a halide or sulfoxylate of the above alcohol (XII) is used, the acid (XI) is generally employed in the form of an alkali metal salt, a silver salt or an organic tertiary base salt. Those salts may be formed in situ by adding simultaneously the acid (XII) and the corresponding base to the reaction system. In this case, a solvent such as benzene, acetone, dimethylformamide and the like is preferably used, and the reaction is preferably conducted by heating the reaction system at or below the boiling point of the solvent used. A preferred halogen for the halide of alcohol (XII) includes chlorine and bromine.

Representative examples of the compounds of this invention are illustrated below, but the present invention is not limited thereto.

PREPARATION 48 Preparation of 3'-phenoxybenzyl-2-(1',2',3',4'-tetrahydronaphthalene-8'-yl)isovalerate (Compound No. 43)

3.95 g (0.015 mole) of m-phenoxybenzyl bromide, 2.32 g (0.01 mole) of 2-(1',2',3',4'-tetrahydronaphthalene-8'-yl)isovaleric acid and 2.02 g (0.02 mole) of triethylamine were added to 50 ml of dimethylformamide and the mixture was stirred overnight at room temperature. The reaction mixture was poured into 50 g of ice-water and extracted with three 30 ml portions of ethyl ether. The combined ether layer was washed successively with 5% hydrochloric acid, saturated aqueous sodium bicarbonate and saturated aqueous sodium chloride and dried over anhydrous sodium sulfate. Removal of ethyl ether by distillation under reduced pressure yielded a crude ester which was then subjected to a column packed with 20 g of activated alumina using benzene-n-hexane (1:3) as an eluent to obtain 3.45 g (83.2% theoretical yield based on the carboxylic acid stating material) of the desired ester as a colorless oily substance.

Most of the important intermediates of the present invention, i.e., disubstituted acetic acid, can effectively be prepared in high yields via one of the alternative procedures (A), (B) and (C) given below. ##STR738## wherein Ar represents an aryl group, R' represents an alkyl, alkenyl or alkynyl group, R" represents hydrogen or a lower alkyl group, and R"' represents a lower alkyl group.

Step 1:

This procedure can be accomplished by alkylating the corresponding arylacetonitrile with an appropriate halide or sulfoxylate of the formula R'--X in an inert solvent (for example, ethers, tetrahydrofuran, benzene, toluene, etc. including liquid ammonia when NaNH₂ and the like is used as a base described below) in the presence of a base such as alkali metals, alkali metal hydrides, alkali metal amides and the like at room temperature or an elevated temperature.

Step 2:

This procedure can be accomplished under the well-known conditions commonly used for hydrolysis of a nitrile group, i.e., by heating the nitrile with a mineral acid or an alkali hydroxide.

Steps 3 and 4:

This procedure can be accomplished by alkylating the corresponding phenylacetic acid or a lower-alkyl ester thereof with an appropriate halide or sulfoxylate of the formula R'--X in an inert solvent in the presence of a base such as alkali metals or hydrides thereof, n-butyl lithium and the like at room temperature or an elevated temperature, and, when the lower-alkyl ester is used for the alkylation, hydrolyzing the resulting ester with an appropriate acid or alkali in the usual manner.

Step 5:

This procedure can be accomplished by reacting an arylmalonic acid ester (which is easily obtainable by carbalkoxylation of the corresponding arylacetic ester) with an appropriate halide or sulfoxylate of the formula R'--X in the presence of an alkali metal alkoxide or an alkali metal hydride as a base in an inert solvent or an alcohol corresponding to the alkali metal alkoxide.

Step 6:

This procedure can be accomplished under the well-known conditions commonly used for hydrolysis of a usual ester, i.e., by hydrolyzing the ester with an acid or alkali to obtain the corresponding dicarboxylic acid followed by heat-decarbonization to obtain the desired carboxylic acid, or can be accomplished by heating the diester with an alkali metal alkoxide in an alcohol whereby the diester is easily converted into a monoester by decarboxylation and hydrolyzing the monoester by the well-known procedure to obtain the corresponding carboxylic acid in high yields.

The preparation of the intermediates, carboxylic acids, can be illustrated by the following Synthesis Examples, but they are not to be construed as limiting the processes or intermediates of the present invention.

SYNTHESIS EXAMPLE 1 α-Isopropyl-4-methoxyphenylacetonitrile

14.72 g (0.1 mole) of 4-methoxyphenylacetonitrile in 10 ml of dry toluene was added to a stirred solution of sodium hydride (2.64 g, 0.11 mole) and isopropylbromide (18.45 g, 0.15 mole) in 100 ml of dry toluene and 10 ml of dry dimethylformamide which was heated at 70° C., in 30 minutes. After addition was completed, the mixture was heated at a temperature of from 80° to 85° C. for 3 hours, and cooled to room temperature then poured into 200 g of ice-water.

Organic layer was separated and the aqueous layer was extracted with ether twice. Combined organic layer was washed successively with water and saturated sodium chloride solution, and dried over anhydrous sodium sulfate. The solvent was removed in vacuo and the residual oil was distilled in vacuo to afford 15.70 g (b.p. 95°-96°/0.15 mmHg, 83.0%) of α-isopropyl-4-methoxyphenylacetonitrile.

In similar manners, following α-isopropylphenylacetonitriles were obtained.

SYNTHESIS EXAMPLE 2 4-Bromo-α-isopropyl-phenylacetic acid

20 g of 4-bromo-α-isopropylphenylacetonitrile was heated with 140 ml of sulfuric acid (50 V/V %) at 145° C. for 6 hours. The cooled reaction mixture was poured onto 150 g of ice, and extracted with ether (100 ml×3). The ether layers were combined and extracted with three 70 ml portions of cold 5% sodium hydroxide solution, and the aqueous extracts were acidified with concentrated hydrochloric acid, and then extracted with ether. The ether extract was washed successively with water, saturated sodium chloride solution, dried over anhydrous sodium sulfate. Removal of the solvent gave 16.9 g (78.2%) of white crystals, which were sufficiently pure for use in next step. A portion of the crystals was recrystallized from benzene, melting point: 97°-98° C.

SYNTHESIS EXAMPLE 4 Diethyl-2-phenyl-2-allyl-malonate

Diethyl-2-phenylmalonate (23.60 g, 0.10 mole, prepared from ethylphenylacetate, Org. Synth. Call, Vol. 2, 288) in 20 ml of dry benzene was added to a stirred solution of sodium hydride (2.38 g, 0.12 mole) in 150 ml of dry benzene at 30°-40° C., and the mixture was kept at 40° C. for 30 minutes. To the white enolate generated was added a solution of allyl bromide (24.2 g, 0.10 mole) in 20 ml of dry benzene at 5° C., thereafter stirring continued at room temperature for one hour.

The reaction mixture was poured into 200 ml of ice-water, and the organic layer was separated. The aqueous layer was extracted with ether (two 100 ml portions). The organic layers were combined, and washed successively with 5% hydrochloric acid, water and saturated sodium chloride solution, then dried over anhydrous sodium sulfate. The solvent was removed in vacuo, and the residual oil was distilled at reduced pressure to afford 24.27 g (87.90%, b.p. 115°-120°/0.25 mmHg) of diethyl-2-phenyl-2-allyl-malonate.

SYNTHESIS EXAMPLE 5 Ethyl-α-allylphenylacetate

Diethyl allylphenyl malonate (20.0 g, 0.072 mole) in 250 ml of dry EtOH was heated under reflux with 7.4 g of sodium ethoxide for 5 hours.

Ethanol was removed in vacuo, and the residue was poured to 75 g of ice-water. The mixture was extracted with ether (three 50 ml portions), ether layer was washed with saturated sodium chloride solution, dried over anhydrous sodium sulfate. Removal of the solvent, and distillation at reduced pressure afforded 12.54 g (b.p. 60°-63°/0.13 mmHg, 85.3%) of the phenyl acetate.

SYNTHESIS EXAMPLE 6 α-Allyl-phenyl acetic acid

Above ethylester was hydrolyzed with 10% potassium hydroxide in methanol at room temperature in a usual manner to give the acid (yield 94.6%, m.p. 34° C.).

SYNTHESIS EXAMPLE 7 Diethyl-2-phenyl-2-propargyl malonate

In a similar manner to Example 4, the malonate was prepared in 81.7% yield (b.p. 115°-120°/0.15 mmHg).

SYNTHESIS EXAMPLE 8 α-Propargyl phenyl acetic acid

20.0 g (0.073 mole) of diethyl-2-phenyl-2-propargyl malonate was hydrolyzed in 330 g of 5% methanolic potassium hydroxide at reflux temperature for 2 hours. Methanol was removed in vacuo, and the residue was dissolved in 150 ml of cold water, acidification with concentrated HCl caused a spontaneous decarboxylation to give the monocarboxylic acid, which was collected by ether extraction. (12.4 g, 97.6%, m.p. 90°-93° C.)

SYNTHESIS EXAMPLE 9

Although the compound which bears an isopropenyl group on α-position such as compounds No. 83, No. 85, No. 125, can be prepared in the usual esterification method using corresponding acid chloride, the double bond of the isopropenyl group readily isomerized to α--β position to make the acid or acid chloride into a mixture of double bond positions. A low yield was attained after chromatographic purification.

Following routes seemed to be better than the usual methods.

3'-Phenoxybenzyl-α-isopropenyl-4-methoxyphenylacetate (Compound No. 82)

(1) To a solution of isopropylmagnesium bromide, which was prepared from 38.1 g of isopropylbromide and 7.3 g of magnesium in 90 ml of dry ether, was added a solution of 4-methoxyphenylacetic acid (16.6 g) in 100 ml of dry tetrahydrofuran at an ice-bath temperature, thereafter the solution was stirred at room temperature for 2 hours. Dry acetone (7.0 g), diluted with 20 ml of dry toluene, was added to the solution, and it was heated to reflux for 5 hours. Cooled solution was acidified with 15% sulfuric acid, the aqueous phase separated, which was extracted with ether. Combined organic layers were extracted with 10% sodium carbonate solution. Carbonate extract was acidified with concentrated hydrochloric acid and extracted with ether. Ether extract was dried over anhydrous sodium sulfate. Removement of the solvent and a recrystallization from ethyl acetate afforded 12.4 g of 4-methoxy-β,β-dimethylatropic acid (55.2%, m.p. 124°-125° C.).

(2) To a solution of 4-methoxy-β,β-dimethylatropic acid (5.0 g) and triethylamine (4.5 g) in 50 ml of dimethylformamide, was added 7.0 g of 3-phenoxybenzylbromide gradually at an ice-bath temperature, and stirred overnight at room temperature. The mixture was poured into cold 10% H₂ SO₄ and extracted with ether. The ether layer was washed with 10% sodium carbonate solution and dried over anhydrous sodium sulfate. Removement of the solvent gave 4.8 g of crude hydroxyester, which was dehydrated with P₂ O₅ in benzene at 80° C. for 13 hours. Filtration, and removement of the solvent gave crude isopropenyl-ester as a dark oil. Purification with silica-gel chromatography afforded 1.9 g of pure ester. (40.5%, n_(D) ¹⁶ 1.5798)

SYNTHESIS EXAMPLE 10 Ethyl-2-(cyclohexane-1'-ol-1'-yl)-butyrate

This was prepared from ethyl-2-bromobutyrate (29.3 g), cyclohexanone (14.7 g) and zinc (9.51 g) in benzene (50 ml) and toluene (25 ml) under usual Reformatsky conditions (b.p. 166°-117°/4 mmHg, yield 16.4 g, 51.0%).

SYNTHESIS EXAMPLE 11 Ethyl-2(cyclohexene-1-yl)-butyrate

Above hydroxyester (16.4 g) was heated under reflux with phosphorous pentoxide (11 g) in 60 ml of dry benzene for 3 hours. Cooled mixture was poured onto 80 ml of cold water, organic layer was separated and washed with saturated sodium chloride solution. Solvent was removed in vacuo, and the residue was distilled under reduced pressure to afford 11.6 g of pale yellow oil. (76.5%, b.p. 88°-92°/4 mmHg)

SYNTHESIS EXAMPLE 12 Ethyl-2,3-diethyl-3-hydroxy-pentanoate

In similar manners described in Example 10, this was prepared from 3-pentanone and ethyl-2-bromobutyrate. (yield 52.8%, b.p. 113°-121°/20 mmHg)

SYNTHESIS EXAMPLE 13

The hydroxyester obtained in Example 12, was dehydrolyzed with phosphorous pentoxide in benzene in a manner described above. (yield 68.2%, b.p. 95°-98°/22 mmHg)

The compounds of the type designated as Compound Nos. 18, 21, 245, 246 and 248 were prepared from the corresponding carboxylic acid or an acid chloride derived therefrom which is obtained by hydrolyzing the ethyl ester prepared in the similar manner as described in Synthesis Examples 10-13. The hydrolysis can be effected by the conventional procedure using sodium hydroxide or potassium hydroxide in methanol at room temperature. The carboxylic acid thus obtained was found to contain a small amount of isomers with respect to double bonds (up to about 10%), but the crude carboxylic acid was subjected to esterification without isolating impurities (isomers) and the product was purified by silica gel chromatography in the final step.

The substituted ester compounds represented by the formula (I) exhibit an excellent pesticidal activity and are expected to have a repelling activity against mites as well as a synergestic activity with other biologically active agents, and can be employed in a wide variety of applications at low cost as pesticidal compositions for use in agricultural and horticultural, forest, sanitary fields as well as in a stockroom of cereals and a composition for controlling mites.

In practical use of these compounds, an appropriate amount of one or more solvents, fillers, diluents, active agents, dispersing agents, surface active agents, spreaders, pressure-imparting agents, emulsifying agents and attractants can be incorporated into the ester compounds of this invention to form an emulsifiable concentrate, a wettable powder, a dust, a granule, a fine grain, a coating agent, a powder, an oil preparation, an aerosol, a mosquito coil, a smoking agent, a fumigating agent, a mosquito insence agent for electrical vaporization, and the like.

The effect of the pesticidal compositions of this invention is further illustrated by the following experiments.

EXPERIMENTAL EXAMPLE 1

An emulsifiable concentrate was prepared by blending each of the compounds (1) to (300) of the present invention, xylol and Sorpol SM-200 (trade name; manufactured by Toho Chemical Co., Ltd.) in a proportion of 25%, 50% and 25% (by weight), respectively. 20 to 25 day-old rice plants after seeding were grown in pots and sprayed with each 300-fold dilute solution of the emulsifiable concentrates thus prepared and a 300-fold dilute solution of carbaryl 30% wettable powder diluted with water as a control commercial agent in an amount of 10 ml/pot in each case and then the pots were covered by a cylindrical metal net. 15 smaller brown planthoppers (Delphecodes striatella Fallen) per group were released in each of the pots treated with the carbaryl wettable powder, and compound (1) to (21) and (102) to (110), while 15 green rice leafhopper (Nephotettix bipuntatus cincticeps Uhler) per group were released in each of the pots treated with the carbaryl wettable powder and compounds (22) to (101) and (111) to (300). Observation on survival one day after the treatment revealed that each of the compounds of this invention exhibits more than 90% killing effect as in the case of carbaryl.

EXPERIMENTAL EXAMPLE 2

Of the emulsifiable concentrates prepared in Experimental Example 1, each of those prepared from the compounds of Table 1 below was diluted with water to each of test concentrations and a 200 ml portion thereof was added to a 300 ml volume beaker. 30 larvae of mosquito per group were released in each of the beaker and allowed to stand for 1 day. Survival was observed and a LC₅₀ (50% lethal concentration) was determined by calculating a percent killing in each case. The results obtained are also shown in Table 1. As a control, lindane emulsifiable concentrate was used.

EXPERIMENTAL EXAMPLE 3

A 2000-fold dilute solution of each of the emulsifiable concentrates prepared in Experimental Example 1 from the compounds of Table 2 below was sprayed on a 12 day-oil seedling of mottled kidney beans after seeding grown in a pot in an amount of 10 ml/pot. The seedling thus treated was cut off and put in a wide opening bottle. In the same manner, an untreated seedling of mottled kidney beans in the same stage was cut off and put in another wide opening bottle. Another fresh seedling was fixed with pins bridging on the former treated seedling and the latter untreated seedling. A leaf of mottled kidney beans on which a number of spider mites (Tetrenychus telarius) were parasitic was placed on the middle of the bridging seedling and allowed to stand for 2 days. Activity on repellency was assessed by investigating the numbers of mites swarming on the treated seedling and the untreated seedling. The assessment standards are as follows:

    ______________________________________                                         -      The ratio of the number of mites on                                                                 1:1                                                       the untreated seedling to that on the                                          treated seedling                                                        +      The ratio of the number of mites on                                                                 up to 4:1                                                 the untreated seedling to that on the                                          treated seedling                                                        ++     The ratio of the number of mites on                                                                 greater than                                              the untreated seedling to that on the                                                               4:1                                                       treated seedling                                                        ______________________________________

Formulation 12

To 1 part of each of Compound Nos. 22, 51, 62, 63, 83, 86, 94, 103, 108 and 125 of this invention was added 5 parts of piperonyl butoxide and the mixture was dissolved in 20 parts of acetone. After 94 parts of 300-mesh diatomaceous earth was added, the resulting blend was thoroughly stirred and mixed in a triturator, and acetone was removed by evaporation to obtain a powder in each case.

EXAMPLE 1

10 third inster larvae of tabacco cutworm (Spodoptera lituna Fabricius) were placed in a glass tray having a high side-wall and a diameter of 14 cm, and 1 ml of a 200-fold dilute solution of each of the emulsifiable concentrates obtained in Formulations 1 and 3 diluted with water was sprayed on the larvae by a sprayer and the larvae thus treated were then transferred into a glass tray containing feeds followed by allowing to stand. Two days after the treatment, greater than 80% of the larvae was found to be killed in each case.

EXAMPLE 2

In an area of the radish field in 5-6 leaf stage, a number of green peach aphid (Myzus persicae Sulza) was atomized with a 200-fold dilute solution of each of the emulsifiable concentrates obtained in Formulations 1, 2 and 4 diluted with water at a level of 424 l/acre. Investigation two days after treatment revealed that the density of aphids is reduced to less than 1/10 the density before treatment in each case.

EXAMPLE 3

A piece of plywood board (15 cm×15 cm) was applied with a 200fold dilute solution of each of the emulsifiable concentrates obtained in Formulations 1 and 2 diluted with water in an amount of 50 ml/m² followed by being dried. The adult german cockroaches (Blatuella germanica Linne) were then brought into contact with the plywood board thus treated for 1 hour, and it was found that more than 80% cockroaches was killed three days after contacting with the board.

EXAMPLE 4

A field of egg-plant (ripe plant) growing a number of larvae of potato lady beetle (Epilachna spersa orientalis Dieke) was atomized with a 200-fold dilute solution of each of the emulsifiable concentrates obtained in Formulation 1 in an amount of 424 l/acre. Investigation on knock-down thirty minutes after the treatment revealed that 90% larvae fell to the ground. A further investigation on density of larvae 24 hours after the treatment revealed that almost 100% larvae had been controlled as compared with the density of larvae before the treatment.

EXAMPLE 5

Forty-five day-old rice plants after seeding were grown in Wagner pots (1/50000) and sprayed with a 400-fold dilute solution of each of the wettable powders obtained in Formulation 8 in an amount of 10 ml/pot. The pots were then covered with a cylindrical metal net and about 20 larvae of leaf hopper (Cicadula sexnotata) were released therein. In each case, more than 80% larvae were found to be killed one day after the release.

EXAMPLE 6

Each of the dusts obtained in Formulation 12 was placed uniformly at the bottom of glass trays having a diameter of 14 cm and a high side-wall in an amount of 2 g/m² and butter was applied to the glass wall except for about 1 cm portion of the bottom. 10 adult german cockroaches per group were then released in the glass trays and, after contacting 30 minutes, the larvae were transferred to a fresh glass container. In each case, more than 80% of the larvae was found to be killed three days after the treatment.

EXAMPLE 7

Each of the oil preparations obtained in Formulation 5 was atomized using Campel's turn table apparatus [Soap and Sanitary Chemicals, Vol. 14, No. 6, 119 (1938)] in an amount of 5 ml. 20 seconds after atomizing, the shutter was opened and 100 adult oriental house flies (Musca domestica vicina Maquant) per group were exposed to the falling atomized fumes for a period of 10 minutes. The flies thus treated were then fed and followed by allowing to stand. More than 80% of the flies were found to be killed in each case.

EXAMPLE 8

Each of the oil preparations obtained in Formulation 7 was sprayed in a (70 cm)³ volume glass box containing about 50 adult oriental house flies in an amount of 0.7 ml under a pressure of 1.5 Kg/cm² and it was found that more than 80% of the flies was knocked down in 10 minutes after the treatment in each case.

EXAMPLE 9

About 50 adult mosquitoes (Culex pipiens) per group were released in a (70 cm)³ volume glass box and sprayed with each of the oil preparations obtained in Formulation 6 in an amount of 0.7 ml under a pressure of 1.5 Kg/cm². It was found that more than 80% of the flies was knocked down in 10 minutes after the treatment in each case.

EXAMPLE 10

A nylon net of about 15 mesh was sprayed on the lower part of a glass cylinder having a diameter of 20 cm and a height of 20 cm and butter was applied on the upper part of the glass cylinder in a width of about 3 cm. Then 20 adult german cockroaches were released therein. The glass cylinder containing the cockroaches was plied on another glass cylinder of the same size, and further another glass cylinder having a diameter of 20 cm and a height of 40 cm was placed thereon. 0.5 ml of each of the oil preparations obtained in Formulation 7 was sprayed from the upper cylinder using a glass atomizer under a pressure of 0.75 Kg/cm² and then sealed followed by allowing to stand. It was found that more than 90% of the cockroaches were knocked down in 30 minutes after the treatment and that more than 90% of the cockroaches were killed 3 days after the treatment.

EXAMPLE 11

Insecticidal activity of each of the aerosols obtained in Formulation 10 on oriental house flies was tested by an aerosol test method using a Peet grady chamber [a method reported in Soap and Chemical Specialities Bluebook (1965)]. The test results revealed that knock-down of more than 80% of the flies was observed in 15 minutes after the treatment and more than 70% of the flies was killed one day after the treatment in each case.

EXAMPLE 12

About 50 adult mosquitoes (Culex pipiens) were released in a (70 cm)³ volume glass box and a mosquito coil both ends thereof having been ignited, was placed in the center of the box bottom. After 20 minutes more than 80% of the flies was found to be knocked down.

EXAMPLE 13

About 50 adult mosquitoes (Culex pipiens) were released in a (70 cm)³ volume glass box and a heating mat obtained in Formulation 11 fixed on an electrothermic plate was placed in the glass box followed by heating to smoke. Within 20 minutes, more than 90% of the mosquitoes was found to be knocked down.

While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
